T0 all 11172/0711/ nuty con/cern:

Be it known that If, ALFRED E. WATKINs, a citizen of the United States, and a resident of South Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Hydraulic Mining Pumps or Rams, ofwhich the`following is a speciiication.

The object of my invention is to produce a new and novel method of using water or other fluids for operating a hydraulic ram or pump for vmining purposes.

Referring to the drawings,-Figure 1 is a vertical sectional view of my invention. Fig. 2 is another vertical sectional view. Fig. 3 is an outside view of my machine. Fig. 4is a crosssection of the same, showingposition of pressure-blocks. Fig. 5 is another cross-section, showing arrangement of springs for retaining blocks. Fig. 6 is a view of head and cranks and arrangement of their proper position.

Corresponding letters and figures denote -like parts in all the views.

25 represents the barrel or plug, made preferably ofsteel, and about six feet long. This plug 25 is provided with recesses which receive the movable blocks 24, the object of which will be hereinafter more fully described. Vithin this barrel or plug 25 are placed the two plungers G and I, made of steel and connected together and operated by rod E and knuckle g. Both of theseplungers pass through leather packing-cups J and K, held in position by the plugs L and Y.` Both of these plungers have a common suction-pi pe, l2, which may be connected to any water-supply by means of a rubber pipe. This suction for the large pump or plunger G is direct. It passes through the plug S', under the suction-valve N, into chamber 27, whence it passes over the valve N, through the passage 43 of cage Q. into pumping-chamber 26. Thesuction for the pressurepump I passes out ofplug S, by way of the channels 12 and 8, into plug l; thence up through scat 5, under suction-valve 2, into chamber 46; thence over valve 2, through the passage 47, into pumpingchamber 48. The forced water from pump G passes through seat O, beneath force-valve M, upunder the valve, and out into chamber 25, whence it passes along the passages 37 37 to the outlets 44 44. The forced water from pressure-pump I passes Serial No. 194.805. (No model.)

up through the seat 4, out from beneath forcevalve 3, into-chamber 34, which has an outlet into the passages 37 37.

For the purpose of throwing the pump G out of aetion,-ar passage, 2S, is provided out of the chamber 27 and above valve N. This passage is controlled by acock or valve,X,and extends through the cock to the exterior, as shown at 29. If the cock X is turned so that passages 28 and 29 are not in connection, the pump G can draw water through its main suction-passage 13; but it' .this passage is made continuous the pump draws in and discharges air, together with `any drip that may pass by.

If this cock is turned so that passages 41 andl 42 do not coincide, the a-ctionof the pump will accumulate pressure readily, but relief therefrom will take place so soon as the passages are continuous by turning the cbck.

It is obvious that when the two plungers G and I are moved the water or fluid is immediately sucked up through their respective valves, and forced outinto the passages 37, through outlet 44, against the movable pressure blocks or rams 24. As the pressure within the machine increases, the plunger G will of necessity require to berelieved of duty, its usefulness being apparent only when runningup the preliminary pressure quickly. To relieve this pump of duty it is simply necessary to turnthe cock X until the passages leading to and from it are in connection. This operation breaks the vacuum and relieves all parts below the force-valve of strain. Thisl operation7 however, does not. interfere with the action of the small pump I7 which continues in operation; and as its area is very small compared with the area of the surface of the movable rams or pressure-blocks a pressure' of several hundred tons can easily be exerted upon any given surface.

In this device I show the pressure of fluid k ularly to breaking down coal orlother minerals.

In that case the barrel and blocks or rams are inserted in a hole in the coal or other mineral, and by forcing out the said blocks by the pressure heretofore explained they rend the coal. By a slight change the pressure of the fluid can be used to lift heavy objects or operate a press, and for such like purposes. The

blocks 24 are held to the barrel by retainingV bolts 21, with heads 22 and springs* 23.

17 is a packing kept in place by plate l19 and screws 38.

is an outlet for the fluid under pressure,to prevent the blocks being thrown entirely out.

49 is a shoe held in position by spring 50, to prevent the blocks sticking in the coal.

A is a housing or support for the mechanism for operating the pumps G and I.4 It is secured to the barrel or plug 25 at 35.

E is the connecting-rodjoining the plunger G to crank D, as shown. The cranks can be operated either by power or hand.

Although I show this mode of operating the plungers, yet I do not confine myself to it, as other modes may and can be used.

The arrangements vof the valves and the keeping them in place can be governed by use, and the man ner of drilling the several passages in the barrel can be as uses suggest, and the plugging up the passages can likewise be left to use.

All the parts are to be made ofthe best material and of any kind.

The advantages gained by the arrangement is greater pressure out of a given quantity of uid.

Vhat I claim is-,f

1. In a hydraulic ram or pump, the plunger G,operated in any manner and passing through packing-cups J and K, held in position by plugs L and Y, all placed within the barrel 25,

in combination with the valves N and M, inlet' 13, chambers 25" and 27, and outlet 37, with opening 44, all placed within the barrel 25, having the movable pressure-blocks 24, substantially as and for the purpose set forth.

2. In a hydraulic ram or pump, the plunger I, 'connected to plunger G, as sho wn,in combination Withthe inlets 8, 11, and 13, valves 2 and 3, chambers 34, 48', and '46, outlet 37 ,with openings 44, and the barrel 25, having the movable pressure-blocks 24, substantially as and for the purpose set forth. 3. In a hydraulic ram or pump, the plungers G and I, in combination with the inlets 8, 11, and 13, the chambers 27 26, 46, 48, 25, and 34, valves N, M, 2, and 3, outlet 37,with openings 44, and the barrel 25, having the movable pressure-blocks 24, substantially as and for the purpose set forth.

4.' In a hydraulic ram or pump, the combination ofthe plungers G and I, the valves N,. M, 2, and 3, the inlets 13, l1, and 8, the chambers 25", 27, 46, and 48, the outlets 37, with openings 44, the passage 28, with cock X, the passages 41 and 42, with cock W, and the barrel 25, having the movable pressure-block 24, substantially as and for the purpose set forth.

5. The movable block 24, with shoe49, held by spring 50, the retaining-bolt 21, the spring 23, the plate 19, and the screws 38, all com bined and arranged for the purpose set forth.
